I have a question: are these standard national specification pipe fittings, or custom-made non-standard ones?

As the title suggests, those who are familiar with pipes used in oil fields, please take a look – what are the standards for the pipe fittings listed below?

I remember that the standards include the American standard ASME B16.11, and the petrochemical standard SH3410; I can’t recall the standards for the chemical industry. I’m not sure whether forged tees or elbows come with threaded connections. Forging is also known as a socket tee or socket elbow; the standard used in thermal power plants is of this square type, but it seems that these units don’t have internal threads and are welded instead
